I think hdldump installed ps2 games to my OS hard drive

I hooked 2 ps2 drives to my computer and ran hdldump (latest version) and queued up about 150GB worth of games to go straight from ps2 - ps2. After about 15 games were transfered i got an error saying that i was out of space. This didnt make any sense because i was using a fresh 250GB hd. I looked at my computer and it said that out of 60 GB, 59.9 was used. I hit properties on all the files in my c drive and they only added up to 4GB. I cant find any files to delete. Doese this mean that games were installed to my OS hard drive? or am i just missing something here. Any help would be appreciated

Which frontend are you using? hdl_dumb doesn't have a queue. hdl_dump "might have" if you know how to write shell scripts.
